Guys, I decided to dig into the problems of immigrants in the US as a test. Here's the outcome:

1. Wrote to 105 immigrants.

2. Got about 20 replies.

3. 10 people gave interviews.

4. Out of 10 interviews, 3 looked like problems for startups.

5. Only 1 agreed to share contact info.

I've published these 3 problems on ProblemHunt.pro.
